Special
futures:

This receiver is very well
designed and well constructed and meets the most modern electronic design
practises at the time.
Panasonic used the best available parts at the time and this is why this
receiver still works fine in 2017.
It is one of the nicest small recveivers Panasonic has built in this time frame.
The LBS version has a discrete power output section with complementary output
transistors.

This solid state reciever uses
all silicon transistors and IC's. The electronic design is very modern in its time.

The output amplifier employs Matsushita NPN-PNP
silicon power transistors and a OTL and OCL output stage,

The tuner section is using a FET
pre-amp and the the IF uses 1 IC and 1 IC detector for FM.
The stereo decoder is of good quality.

Panasonic made 2 versions of this
receiver, this LBS version with discrete audio output power section,
and a non LBS simpler version with output power IC's.

It offers LW and MW too.

Modifications:

The power supply is not to modern
standards anymore, you can update it with 4700 uF cap or better.
The sound and the power capability will improve.
With a little redesign of the power supply you can improve the current
capability of the power supply
you will get a 2x10 Watts RMS amp at 8 Ohms.
The reception meets
modern standards, with quite moderate noise figures and acceptable sensitivity.

Set the power transformer voltage
setting from 220 V to 240 V
in Europe.

Updating this receiver is very rewarding.

Main PCB ^

The power amplifier and power supply, as you can see best parts
are used and its very well constructed.
Heatsinking can be improved as I did above.
